Knowledge Accumulates Over Generations

One of the central takeaways from Chuck Klosterman’s book is that throughout history many well-verified “truths” about how the world works have, in time, been proven wrong. He provocatively asks: Which assumptions about the world do we hold dear today that subsequent generations, benefitting from greater scientific discovery, will laugh at?

You can learn this lesson vividly in the arena of building engineering and home repair, as I have.

Consider a building structure that was originally built 100 years ago but has been updated over time. An engineer will inspect the building and say, “Oh, that foundation work utilized a technique that was common in 1980.” Or: “That way of supporting a second story addition was popular in the 70’s.” A specific building technique is easily timestamped based on the prevailing knowledge at that time. With the punch line being: There’s a different best practice today. “In 2017, we do it differently.” And, usually (but not always) — it’s a better technique.

It’s inspiring to see how building engineers continue to iterate their approach. And it occurred that it’d be amusing if management consultants similarly couched their advice in before-and-after timestamped language. “That way of doing performance management was popular in the 80’s, but we know better now.” “Structuring your decision making that way was popular in the 90’s, but we know better now.”

Related, somewhat of a counterpoint: The always provocative Robin Hanson says one of the big neglected problems in the world is that each generation has to re-learn lessons during its individual lifetimes.
